I was just wondering if the blood tests you had were done in the ER or urgent care unit, where cardiac enzymes would most likely be checked, and would be checked 100% of the time with active chest pain.
You could call your PCP and ask if these tests were done along with the general blood counts.
I can't really answer this with the information I have available. If I am asked if you should go to the ER and you are having chest pain, I have to say yes because we can't talk about and I can't see EKGs, Echos, etc.
Your symptoms do sound like anxiety, but I can't make the diagnosis of the internet is someone having active pain.
A stress test is always important to rule out ischemia and I did not see that on your list above. People with continuous chest pain and normal EKG and normal cardiac enzymes have no cardiac chest pain. you cannot have anginal chest pain continuously and not have a heart attack. You have not had enzymes check or a stress test, so I would need more information to comment.
If you are still having pain and think it is cardiac, you should be evaluated.
I hope this helps.
